Coaxial Cable

What is it?

• Structure: A single wire wrapped in foam insulation, surrounded by a braided metal shield, and covered with a plastic jacket. It comes in various thicknesses.

• Types:

  • Baseband Coaxial Technology: Utilizes digital signaling, where the cable carries only one channel of digital data.
  • Broadband Coaxial Technology: Transmits analog signals and supports multiple channels.

Why is it used?

• Advantages:

  • Due to shielding, it can carry a wide bandwidth of frequencies.
  • Suitable for applications like cable television.

• Disadvantages:

  • More difficult to install compared to twisted pair cables.
  • More expensive than twisted pair cables.
